CCM8C Molded Case Circuit Breaker
product detail
General
YCM8C series external circuit breakers are suitable for distribution networks with AC 50Hz or 60Hz, rated insulation voltage of 1000V, rated voltage of 400V and below, and rated current of 1000A. Under normal circumstances, the circuit breaker can be used for the infrequent on-off control of the line and the infrequent start of the motor respectively.
Standard:IEC60947-2;IEC60947-1;
Operating Conditions
1. Extreme temperature range for storage and transportation: -10°C to 85°C;
2. Operating range: -10°C to 75°C;
3. Reference temperature: 55°C;
4. Atmospheric conditions: The maximum temperature is 75 ℃ and the maximum relative humidity is 95%;
5. External magnetic fields at the installation site must not exceed 5 times the strength of the earth's magnetic field, and the product should be kept away from strong electromagnetic interference (such as high-power motors or inverters). There should be no explosive or corrosive gases, no exposure to rain or snow, and the environment should be dry and well-ventilated;
6. Pollution level: level 3; installation category: category III.
